[Nuclear processes on operation of linear accelerators (author's transl)]

The primary nuclear reactions possibly occurring in accelerators operated on an energy level between 8 and 20 MeV are outlined, and their probability is estimated. Furthermore, the authors discuss which photoneutron rates par micron As are to be expected in case of different threshold energies in a tungsten sheet with a thickness of 6 mm and which secondary nuclear processes are induced by the photoneutrons.
